Turbine powered

Completion reaming system

Completion reaming system

The Turborunner™ is a high-speed reaming system that enables Completions teams to land completions at target depth and safeguard valuable completion assemblies.

The unique design combines high speed rotational reaming with very low operation pressure and completely isolates the downhole assembly from the dynamics and vibrations of the reamer shoe. This allows the turbine to slow or even stall without any reactive mechanical torque or uncontrolled pressure spikes being transferred to the completion or the liner hanger.

There is no need to rotate the completion string, protecting low-torque or low strength completion equipment.

A rugged and reliable tool, the Turborunner™ ensures completions access all planned reserves whilst significantly reducing Flat Time and the risk of off-depth completions.
